Hi to all,am thinking of making a toy version of a laser designator /reflections detector system.Environemnt would be a room, robot(tracked probably) to move around floor to seek out the object the reflections are coming from --- such as shiny metal box, plastic block, or a small shiny toy.The user would designate the destination by shining laser at the object.

Question is really is this likely to be possible ? have not seen any projects doing this. But have come across projects where the 'target' has several laser emitting diodes attached, and detector is made from matching sensors.I suspect that the intensity from laser reflections is just way too low for sensors to pick up.

I will go ahead with that project now. As it progresses no doubt there will be problems. When I have something specific to ask for advice on, after some researching via google but not getting the answers, I will return to the forum.
